It is time to review your privacy settings.

Now imagine all of the data captured through your Facebook use since you joined. Crap.

In college, tons of people liked (at least on Facebook) drinking, hooking up, smoking weed, partying, sleeping late, etc. Now, Facebook has given users the power to find which of those poor saps left that information public.

Here’s an example that could ruin marriages. A recent app, Bang with Friends, has been going viral on Facebook and in tech press. Imagine Hot or Not except you’re picking folks you would like to hook up with – by folks, I mean friends. Don’t worry… they’ll only see it if they want to hook up with you too. A little panic, but many are okay with that. For single folks, go for it. But, that would be too easy.

Suppose someone is married. They add Bang with Friends and remove it from their activity feed so their spouse doesn’t see it. Whew. Close one. They carefully prune through their friends to pick the potential hook-ups that would use discretion to protect the sanctity of their marriage (cough). Not so fast. Most relationship statuses are public. Facebook shares your app usage. Want to see what that looks like?
